greedy:         (alt_input = false; eat_input = true)
    L opens/closes the menu
    while the menu is open, the game receives no inputs
    D-Pad/Joystick/C-Buttons navigate through items and pages
    A select menu items
    B/R go back a menu (or closes)
    Z hides the menu without closing

greedy alt:     (alt_input = true;  eat_input = true)
